Good Day I battle with 2 units on a Tele Eye 3216 V 4.13 bios on a 24 hours basis we get from channel 1-8 some interference and picture jumping around as if the pictures has bursting and horisontal stripes between 30 minutes to an hour a time and then it stops and work 100%. Any advise to isolate the problem? Thx B Cilliers
